Crossplay

Is Dungeons & Dragons: Dragonshard crossplay?

Dungeons & Dragons: Dragonshard is only released on one platform, so there is nothing to cross-play with.

Dungeons & Dragons: Dragonshard is a real-time strategy role-playing video game, developed for Microsoft Windows by Liquid Entertainment, and published by Atari in 2005. It takes place in Eberron, one of the official Dungeons & Dragons campaign settings. The game combines elements of traditional real-time strategy gameplay with role-playing elements such as hero units, and questing. Dragonshard includes two single-player campaigns, single-player skirmish maps, and multiplayer support. The single-player campaign follows the struggles of three competing factions to gain control of a magical artifact known as the Heart of Siberys. Although Dragonshard was billed by Atari as "the first Dungeons & Dragons real-time strategy experience,"[2] Stronghold (1993) precedes it by over a decade.[3]
